### OpenAPI

**FastAPI** 使用定義 API 的 **OpenAPI** 標準來生成一個 「schema」 與你的所有 API。

#### 「Schema」

「schema」是對某個事物的定義或描述。它並不是實作它的程式碼，而僅僅是一個抽象的描述。

#### API 「schema」

在這種情況下，<a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> 是一個規範，它規定了如何定義 API 的 schema。

這個 schema 定義包含了你的 API 路徑、可能接收的參數等內容。

#### 資料 「schema」

「schema」這個術語也可能指某些資料的結構，比如 JSON 內容的結構。
